Local musician Andrew Dezarn lives with his girlfriend and two dogs on their boat in Boston Harbor.

In his current living conditions, he says subfreezing temperatures are hardly a bother.

“The boat is shrink-wrapped, so you get the greenhouse effect from the sun shining in and also the wind doesn’t get into the cracks and crevices,” Dezarn told WBZ NewsRadio 1030’s Karen Twomey. “The boat has two central heating systems and the engine block heaters radiate heat up through the floor all the time.”

Dezarn says it gets so warm sometimes, he has to turn off one of the heaters.
